Funny you ask! I just edited this in, realizing it was relevant.

It's quite odd, this is with Fedora -- the current/latest release for about the past year (34 through 36).

It's seen quite a healthy number of 5.x kernels, but every time I try to go without I reluctantly have to build it again

It'll work fine, for a time, but when I really put stress on that link it'll drop

Edit: This is trained at multi-gig too -- going to a 10GbE Mikrotik switch.

I haven't tried testing reliability at 1G -- it's probably better, but I'd like the speed... I still have yet to try a 6.y kernel on it
